Bug#1049903: petsc: misbuild with gcc-13

Hi Steve, thanks for the bug report.

With patching, wouldn't it be simpler to just add -lstdc++ to
CXX_LINKER_FLAGS at configuration time (in debian/rules) rather than
hacking the upstream detection code?  As you say, hardcoding in the
upstream scripts doesn't really resolve the underlying problem.

Is there a reason why hacking CXX_LINKER_FLAGS in debian/rules doesn't
fix the build?
